[0028] like Figure 1-4 As shown, this embodiment provides a high-precision 3D camera with internal fine adjustment, including a shell 1, wherein the shell 1 includes a bottom shell 11 and a surface cover 12, wherein the bottom shell 11 and the surface cover 12 are fixed to each other by bolts, and can be disassembled by unscrewing the bolts, wherein a laser module 2, a lens module 3, a chip module 4 and a processing module 5 are arranged inside the bottom cover, wherein the processing module 5 is fixedly installed on the inner side of the bottom shell 11, and the processing module 5 is connected to the chip module 4 by a cable, and the chip module 4 is fixedly installed on the lens module 3, wherein the bottom shell 11 is embedded with a lens 13 at a position corresponding to the output end of the lens 32; and the bottom shell 11 is provided with a laser 22 hole 14 at a position corresponding to the output end of the laser 22.
[0029] The laser module 2 includes a laser 22 and a first fine-tuning mechanism 21 for driving the laser 22 to move along the axial direction of the laser 22 (the axial direction of the laser 22 is the direction in which the laser 22 is emitted).
[0030] Specifically, the first fine-tuning mechanism 21 includes a first guide rail 211, the length direction of the first guide rail 211 is arranged parallel to the axial direction of the laser 22, the first guide rail 211 is bolted and fixedly connected to the inside of the shell 1, the first guide rail 211 is slidably connected to the first slider 212, the surface of the first slider 212 is bolted and fixedly connected to the first adapter plate 213, the side of the first adapter plate 213 is connected to the first tooth plate 214, the teeth of the first tooth plate 214 are meshed with the first adjusting knob 216, the bottom of the first adjusting knob 216 is integrally formed with a pinion, the pinion is meshed with the teeth of the tooth plate, the surface of the first adapter plate 213 is bolted and fixedly connected to the laser clamp 215, the laser 22 is embedded in the laser clamp 215 for fixation, and the first adjusting knob 216 is detachably connected to the inside of the shell 1. By rotating the first adjusting knob 216, the small gear at the bottom is driven to rotate, thereby driving the toothed plate to move. The movement of the toothed plate drives the first adapter plate 213 to move in the direction of the guide rail, thereby adjusting the position of the laser 22. After the adjustment is completed, the first adjusting knob 216 can be removed to save space, and auxiliary guidance is performed through the guide rail and the slider to make the adjustment more precise.
[0031] Furthermore, a plurality of first positioning holes are provided on the first adapter plate 213, and a first positioning screw 218 is detachably connected to the first positioning hole. After the adjustment is completed, the plurality of first positioning screws 218 are fixed to the housing 1, thereby fixing the position of the laser 22 to avoid movement during subsequent use.
[0032] Furthermore, first limit blocks 217 are respectively bolted and fixedly connected at both ends of the first guide rail 211. The first limit blocks 217 prevent the first slider 212 from derailing, thereby limiting the movement of the laser 22.

A pinion is integrally formed at the bottom of the second adjusting knob 316, and the pinion is meshed with the teeth of the second tooth plate 314. The second adjusting knob 316 is rotated to drive the second tooth plate 314 to move, thereby driving the lens 32 to move on the guide rail to adjust the lens 32. The second adjusting knob 316 is detachably connected to the inside of the housing 1, and the second adjusting knob 316 can be disassembled and taken out after the adjustment is completed, and does not need to be retained in the housing 1, thereby reducing gravity and reducing occupied space.
